VEHICLE-WHEEL.

Specification of Letters Patent.

Patented Apr. 18, 1916..

Application filed August 19. 1915. Serial No. 46.337.

To all Iv/tom it may conrrarn lie it known that I 'liiouxs E. Mummy, :1 ritizen of the l nited tates, residing at New York. in the eounty of Xew York and State of New York. have invented a Certain new and useful lmpiovement in Vehicle- Wheels of whieh the following is a specifiration.

The invention relates to vehicle wheels formed wholly of sheet metal, and CODSlStS in the eonstruetion oi said wheel and of the means for rendering the rim demountable, hereinafter more partieularly set forth.

in the aeeompanying dinnings-Figure l is a lace view of my wheel. a portion of the hollow fixed rim being broken away to show the internal eonstruetion. Fig.- 2 is a section on the line 2, .2 of Fig. 1.

Similar letters of reterenee indicate like parts.

The spokes A are tubular and preferably formed integral with the web it at their inner ends, in which web there is a central opening (l for the reeeption of the hub.

The fixed rim is quadrangular in cross StltillOfl, having side walls D. E provided with flanges l upon which are seeured the eirouml'erential outer wall (l. The spok s A pass through openings in the inner wall ll of said fixed rim and abut against said outer wall.

In order to secure the movable rim l to the fixed rim. I provide (clamping devices, generally indicated at J. The fixed member K of each elamp is permanently seemed to side wall l) of the fixed rim and has a shoulder.

In order to secure the rim l to the, fixed rim, I provide pairs of clamping devices, generally indieated at J. l may apply one pair of said clamping devices to eaeh spoke or to alternate spokes, as shown in Fig. 1. The lixed member K of eaeh clamp, whieh may he homogeneously united, as by welding, to the side wall E oi the fixed rim, has a shoulder to reeeive the flange on said wall and the edge of wall ll. and a eurved extension L which bears against the rim l. The headM of a bolt N may be welded to said member K. Said bolt passes through openingsin the side. walls D, l) and the spoke A. The protruding portion of said bolt beyond wall D passes through an opening in the movable clamping member 0, whieh also has a shoulder to receive the flange on wall D and an extension P bearing on rim I outside of side wall D. The outer portion of bolt N is lhreaded to receive the (damping nut Q. The opening in member should be large enough to allow said men'iber to turn freely on bolt when nut Q loosened. and t insure this I prefer to form a gap R in said extension 1 eonimnnicating with the said opening.

The spokes may he homogeneously united to the fixed rim to which the movable rim is secured b v setting up the nut (Q. When it is desired to remove the rim I, the nut Q is loosened and the movable members 0 are turned on the bolts X so as to clear the movable rim -as. l'or example, into the position shown in dotted lines. The movable rim may then easily he slid off the fixed rim in the direction of the arrow, Fig. 2, and a new movable rim substituted, the movable clamping members being finally returned to their original position and the nuts Q again set up.

The objeet ol' the flanges F on the side walls oi" the fixed rim is to furnish a wider support for the outer (circumferential wall (1, thus enabling: that wall. to be made wider than the inner or bottom wall H of the hollow rim, and so to provide for a sup port for a movable rim wider than said wall ll.

I claim:

1. A metal vehiele wheel, eomprising a' hollow fixed rim quadrangular in cross section, tubular spokes entering said rim. a Il'l()\';ll)l( rim seated on the outer eircumfeu ential wall of said fixed rim, clamping means for said movablerim, comprising movable and fixed members respectively seated against the side walls of said fixed rim. and bolts passing through said side.

walls. said clamping members and said spokes.

"2. metal vehicle wheel, comprising a,

hollow lixed riin quadrangular in cross. see-' tion having out-turned flanges on the outer edges of its side Walls and its outer circumferential Wall extending over and seated upon said flanges, a movable rim seated on said outer Wall, clamping means for said movable rim, comprising movable and fixed members respectively seated against said side walls of said fixed rim and recessed to receive said flanges and the edges of said movable rim, and means for releasably se- 10 curing said movable members in place.

In testimony whereof I-have affixed my signature in presence of two witnesses.
